Among the parts of a toilet seat that wear with time are the toilet seat hinges. These hinges are located at the rear of the toilet seat. They serve to raise and lower the seat. Over time, these hinges break or wear out, requiring replacement. If your toilet seat hinges are broken, you do not need to change the whole toilet seat, only the hinges. With the right tools and spare parts, you can easily replace your toilet seat hinges.

Step 1 - Remove the Seat

Lift the toilet seat lid. You will see two hinges at the base. Remove the screws that hold the hinges to the lid and remove the lid.

Step 2 - Remove the Protective Caps

Open the protective caps on the hinges. Use the flathead screwdriver to pry open the protective caps on the hinges.

Step 3 - Remove the Bolts

Under each of the protective caps are bolts held in place by a nut. Remove them by unscrewing the nut with your hands.

Step 4 - Remove the Hinges

Once the bolts are free, remove the hinges.

Step 5 - Purchase New Hinges

Take the old hinges with you to the hardware store and get replacements for them. Ensure they are the same size and compatible with the toilet lid.

Step 6 - Fix the Hinges

Remove the hinges from the packaging and attach them to the toilet seat, making sure the screws are tight.

Step 7 - Remove the Protective Caps

Remove the protective caps from the hinges so they can be inserted into the toilet base.

Step 8 - Align the Hinges

Align both hinges to the holes on the base of the toilet seat.

Step 9 - Fix the Bolts


Once you have inserted a bolt with its washer into the hole on the toilet base, screw it onto the bolt on the bottom of the toilet. Use a screwdriver to tighten the bolt, while holding the nut with your hand.

Step 10 - The Second Bolt

Use the same method as in Step 9 to affix the second bolt. Make sure it is tightened properly.

Step 11 - Replace the Protective Caps

Replace the protective caps on each bolt with the hinges.

Step 12 - Check the Toilet Seat Hinges

Check the toilet seat hinges by raising and lowering the toilet seat. It should work properly if you have followed the steps.

That’s it. You have successfully replaced the toilet seat hinges for your toilet.
